Self-consistent 3D modeling of Mercury's solar wind- surface-exosphere interaction
It can be speculated that the composition of Mercury’s exosphere is related to the composition of Mercury’s crustal materials. If this relationship is true, then inferences regarding the bulk chemistry of the planet might be made from a thorough exospheric study. The most vexing of all unsolved problems is the uncertainty in the source of each component which depends highly on the solar activit...
متن کاملSelf-consistent Coronal Heating and Solar Wind Acceleration from Anisotropic Magnetohydrodynamic Turbulence
We present a series of models for the plasma properties along open magnetic flux tubes rooted in solar coronal holes, streamers, and active regions. These models represent the first self-consistent solutions that combine: (1) chromospheric heating driven by an empirically guided acoustic wave spectrum, (2) coronal heating from Alfvén waves that have been partially reflected, then damped by anis...
متن کاملSelf Organising Maps of Solar Wind Structures
Two Self Organising Map neural networks have been trained to classify structures in the solar wind, one using Bz, n, and V, and the other using p and E. The classification has been done for values of the Dst index at -50, -100, -150, -200, and -250 nT, for events where the gradient of n and V exceeded a certain threshold (shocks as a result of coronal mass ejections) and for events where the gr...
متن کاملSelf-consistent theory of turbulent transport in the solar tachocline
Aims. To understand the fundamental physical processes important for the evolution of solar rotation and distribution of chemical species, we provide theoretical predictions for particle mixing and momentum transport in the stably stratified tachocline. Methods. By envisioning that turbulence is driven in the tachocline, we compute the amplitude of turbulent flow, turbulent particle diffusiviti...
متن کاملFoundations of self-consistent particle-rotor models and of self-consistent cranking models
The Kerman-Klein formulation of the equations of motion for a nuclear shell model and its associated variational principle are reviewed briefly. It is then applied to the derivation of the self-consistent particle-rotor model and of the self-consistent cranking model, for both axially symmetric and triaxial nuclei. Two derivations of the particle-rotor model are given. One of these is of a form...
